Description

According to this thread, only Amazon's proprietary hadoop-core.jar enables S3 to work on with Pig. Apache Pig does not work.

Example:

Apache Pig branch-0.9 as of today:

hadoop@ip-10-195-159-114:~$ pig/bin/pig
grunt> cd s3://elasticmapreduce/samples/pig-apache/input/
2012-02-29 05:45:22,282 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2999: Unexpected internal error. This file system object (hdfs://10.195.159.114:9000) does not support access to the request path 's3://elasticmapreduce/samples/pig-apache/input' You possibly called FileSystem.get(conf) when you should have called FileSystem.get(uri, conf) to obtain a file system supporting your path.
